Three dimensional card

ABSTRACT

A sign and a method for its manufacture include a lenticular split image which is process printed onto the second surface of a lenticular lens layer. Additionally, selected portions of the image are masked by a lenticular split covering, and a reflective layer is mounted against the lenticular lens layer, with the image and the covering therebetween. This gives a shiny appearance to the unmasked portions of the image and gives a flat appearance to the masked portions of the image. The lenticular split image and the lenticular split covering each respectively include a plurality of separate images and a plurality of separate aspects which include a plurality of strips. In order to obtain a 3-D effect for the sign, the plurality of lenses in the lenticular lens layer are aligned in register with the corresponding juxtaposed strips of both the lenticular split image and the lenticular split covering.

FIELD OF THE INVENTION

The present invention pertains generally to signs and trading cards.More particularly, the present invention pertains to flat signs whichpresent a three dimensional impression. The present invention isparticularly, but not exclusively, useful as a sign which presents theimage of an object with both a three dimensional impression and avariation in visual texture which includes both a shiny and a flatappearance.

BACKGROUND OF THE INVENTION

The effectiveness of signage to disseminate information is in large partdependent on the attractiveness and visual presentation that is providedby the sign. For most applications, it is necessary, or desirable, tohave attractive and eye-catching signage. This is so regardless whetherthe purpose of the sign is to merely entertain viewers or to enticesomeone into purchasing a particular product or service. In attempts tomake a particular sign distinctive and memorable, various techniqueshave been employed to create a notable visual impression with the signand to thereby further its purpose.

A distinctive visual effect which has often been employed in signageinvolves giving the sign a three dimensional (3-D) appearance. Indeed,various techniques for creating such an appearance have been used. Ageneral overview of these efforts is presented in an article written byAlfred DeBat entitled "A brief history of 3-D photography". Thisparticular article appeared in the July 1992 edition of ProfessionalPhotographer.

Another distinctive visual effect that has recently appeared in variouscommercial signs, and particularly on trading cards, involves visualtexturing which gives signage a mix of both shiny and flat appearances.This particular effect is taught and disclosed in U.S. Pat. No.5,106,126 which issued to Longobardi et al. for an invention entitled"Process Printed Image with Reflective Coating" which is assigned to thesame assignee as the present invention. Yet another distinctive visualeffect which has been successfully incorporated into signage isdisclosed in U.S. Pat. Nos. 4,933,218 and 5,082,703 which both issued toLongobardi for an invention entitled "Sign with Transparent Substrate",and which are assigned to the same assignee as the present invention.This effect is a 3-D depth enhancement which is achieved by depositingan extraordinarily thick ridge of ink onto selected portions of animage.

While the above mentioned technologies are exemplary of developmentswhich have individually added to the attractiveness and effectiveness ofsignage, the present invention recognizes that the combination ofvarious technologies in the manufacture of a single sign can alsoimprove the appeal of signage. Specifically, the present inventionrecognizes that several technologies can be effectively combined in themanufacture of a flat sign with a three dimensional appearance thatcauses the separate technologies to complement each other.

In light of the above it is an object of the present invention toprovide a flat sign which has a 3-D appearance that includes variationsin its visual texture. Another object of the present invention is toprovide a flat sign which has a 3-D appearance that includes depthenhancements. Still another object of the present invention is toprovide a method for manufacturing a flat sign with a 3-D appearancewhich has variations in the appearance that include different visualtextures and enhancements in depth perception. Another object of thepresent invention is to provide a flat sign with a 3-D appearance thatis relatively easy to manufacture and comparatively cost effective.

SUMMARY OF THE INVENTION

A sign, such as a trading card, includes a clear lenticular lens layerwhich has an image made of light transmissive inks that is processprinted onto the second surface of the lens layer. Specifically, for thepresent invention the process printed image is a lenticular split image.As used here, the descriptor "lenticular split" indicates that theso-described visualization of an object (e.g. image, design) is actuallya composite of several separate visualizations. Specifically, each ofthe separate visualizations that together make up the lenticular splitvisualization include a plurality of strips, and these strips arelocated in an ordered juxtaposition with the strips of other separatevisualizations to create the lenticular split visualization.

A lenticular split covering, preferably made of an opaque white ink, isdeposited onto selected portions of the lenticular split image to maskportions of the image. Thus, the lenticular split image can have bothmasked and unmasked portions. A reflective layer of metallized mylar isthen laminated against the lenticular lens layer with both thelenticular split image and the lenticular split covering positionedtherebetween. The result is that the unmasked portions of the lenticularsplit image will have a shiny appearance, and the masked portion of thelenticular split image will have a relatively flat appearance.

For added visual effect, an extraordinarily thick ridge of lighttransmissive ink can be deposited onto the second surface of thelenticular lens layer together with the lenticular split image. Thisextraordinarily thick ridge of ink can be specifically depositeddirectly onto any design that may be incorporated into the image, oralong the edge of the design. For purposes of the present invention, thethickness of the extraordinarily thick ridge of ink will be at leastthree times thicker than the thickness of a normally process printedink.

For reasons well known in the pertinent art, when a lenticular lenslayer is placed in register over a lenticular split image, the result isa visualization having an apparent three dimensional effect. For thepresent invention, this three dimensional effect is enhanced byvariations in the visual texture of the visualization that result fromplacement of the lenticular split covering. Specifically, for the signof the present invention, the visualization is presented with someportions of the lenticular image which are unmasked and therefore shiny,and other portions of the lenticular split image which are masked andtherefore flat in appearance. Additionally, some parts of thevisualization can be given depth enhancement by being high-lighted withan extraordinarily thick ridge of ink.

In the manufacture of a sign according to the present invention, pictureparts of the object to be presented on the sign are differentiated and,according to the desired three dimensional effect for the sign, arearranged to have different depth distances from a camera position. Theobject is then photographed with the camera from several differentparticularly selected perspective viewpoints. This is done with alenticular lens on the camera to create individually separate images ofthe object from each viewpoint. Each of these separate images of theobject includes split strips which are located in an orderedjuxtaposition with strips from the other separate images. Together,these strips create the lenticular split image of the object which isthen process printed onto the second surface of a clear lenticular lens.

In a manner similar to that described above for the lenticular splitimage, a lenticular split covering is also prepared. To do this, thoseportions of the various object parts that are to have a generally flatappearance are first selected and identified. Negatives of theseselected portions are then arranged to have the same depth distance fromthe camera position that was previously established for the particularportion of the object that is to be covered. The negatives are thenphotographed with the camera from the same different particularlyselected perspective viewpoints as were previously used in thepreparation of the lenticular split image. As with the image itself,separate aspects of the covering are created. Each of these separateaspects of the covering include strips which are located in an orderedjuxtaposition with corresponding strips from the other separate aspects.This creates the lenticular split covering. The lenticular splitcovering is then process printed with a white opaque ink onto thoseportions of the lenticular split image which are to be masked.

As indicated above, an extraordinarily thick ridge of ink can bedeposited onto selected areas of the lenticular split image. Forpurposes of the present invention, the extraordinarily thick ridge ofink is deposited using a silk screen process and is positioned, asdesired, onto designs in the lenticular split image or at the edge ofsuch designs.

A reflective layer, preferably made of a metallized mylar, is thenlaminated against the lenticular lens layer with the lenticular splitimage, the lenticular split covering, and the extraordinarily thickridge of ink positioned between the reflective layer and the lenticularlens layer. This reflective layer will give a shiny appearance to theunmasked portions of the lenticular split image but will not affect theflat appearance which is given to those portions of the lenticular splitimage that are masked by the lenticular split covering. Further, abacking sheet can be attached to the reflective layer opposite thelenticular lens layer to give stiffness to the sign and to presentanother surface on which information may be printed.

The novel features of this invention, as well as the invention itself,both as to its structure and its operation will be best understood fromthe accompanying drawings, taken in conjunction with the accompanyingdescription, in which similar reference characters refer to similarparts, and in which:

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring initially to FIG. 1, a sign according to the present inventionis shown and generally designated 10. As will be appreciated, sign 10can actually be any medium, such as a picture, a design, a placard or atrading card which visually presents information for the viewer.Further, sign 10 can present any image or design of any object that isto be presented by the sign 10 for viewing. For purposes of disclosureof the present invention, sign 10 is shown with the image of design of aclover leaf 12, a diamond 14 and a heart 16.

As perhaps best seen in FIG. 2, the sign 10 includes several components.One such component is a lenticular lens layer 18 which is preferablymade of a clear plastic, and which has a first surface 20 and a secondsurface 22. The distinction between first surface 20 and second surface22 being that a viewer will look onto the first surface 20 when viewingthe sign 10. Second surface 22 will thus be behind first surface 20.Further, the lenticular lens layer 18 includes a plurality of generallysemi-cylindrical convex shaped lenses 24 which are linearly alignedside-by-side in juxtaposition on the first surface 20 of lenticular lenslayer 18. For the purposes of the present invention, when measured in adirection perpendicular to the length of the individual lenses 24, thereshould be somewhere between fifty and one hundred and fifty lenses 24per inch. As is well known in the art, the actual number of lenses 24per inch can vary somewhat according to the desires of the manufacturer.

FIG. 2 also shows that the sign 10 includes a lenticular split image 26.Specifically, for sign 10, the lenticular split image 26 includes images(or designs) of the clover leaf 12, the diamond 14, and the heart 16.The actual composition of lenticular split image 26 is discussed ingreat detail below. Suffice it to say, at least for the time being, thatlenticular split image 26 is made of any light transmissive inks, i.e.transparent or translucent inks, which are well known in the pertinentart. Further, as indicated in FIG. 2, and in FIG. 3, the lenticularsplit image 26 is deposited directly onto second surface 22 oflenticular lens layer 18.

Still referring to FIG. 2, it will be seen that sign 10 includes alenticular split covering 28 which, for purposes of discussing thepresent invention, is shaped in the likeness of heart 16. As intendedfor the present invention, lenticular split covering 28 is made of anopaque ink (e.g. white ink) and is deposited against the second surface22 of lenticular lens layer 18. Lenticular split covering 28, however,is deposited on top of lenticular split image 26 to place the lenticularsplit image 26 between lenticular split cover 28 and lenticular lenslayer 18.

As shown in FIG. 2, lenticular split covering 28 includes only alikeness of the heart 16. There is no corresponding likeness for eitherthe clover leaf 12 or the diamond 14. Consequently, that portion of thelenticular split image 26 which includes the heart 16 will be masked bythe lenticular split covering 28. On the other hand, those portions ofthe lenticular split image which include the clover leaf 12 and thediamond 14 will be unmasked. For reasons to be subsequently discussed,the difference between the masked portions of lenticular split image 26(i.e. heart 16) and the unmasked portions of lenticular split image 26(i.e. clover leaf 12 and diamond 14) gives a visual texturing to sign10.

The visual texturing referred to above occurs because sign 10 furtherincludes a reflective layer 30. Specifically, the reflective layer 30 ispreferably a metallized mylar which is laminated against the secondsurface 22 of lenticular lens layer 18 with both the lenticular splitimage 26 and the lenticular split cover 28 located therebetween.Although metallized mylar is suggested here, it is to be appreciatedthat any material which will provide a specular reflection (i.e. shinyor mirror-like reflection) will be suitable for purposes of the presentinvention. The result is that light will pass through the lighttransmissive inks of lenticular split image 26 and reflect from eitherthe opaque ink of lenticular split covering 28 (masked portions oflenticular split image 26) or from the reflective layer 30 (unmaskedportions of lenticular split image 26). It happens that the light thatis reflected in the masked portions will give the lenticular split image26 a relatively flat appearance and the light that is reflected in theunmasked portions will give the lenticular split image 26 a relativelyshiny appearance. It is the contrast between the shiny (unmasked) andflat (masked) portions of sign 10 that give it visual texturing.

FIG. 2 shows that sign 10 also includes a backing 32. For the presentinvention backing 32 can be made of any material which provides asupporting structure for sign 10. Additionally, backing 32 may be usedto present printed information that can be viewed from the back of sign10.

FIG. 3 shows an additional component for sign 10 which can be optionallyincluded to enhance the perception of depth in sign 10 for the viewer.Specifically, this component is an extraordinarily thick ridge of ink 34which can be selectively applied to the lenticular split image 26. Forthe present invention, the extraordinarily thick ridge of ink 34 is atleast three time thicker than a normally process printed ink. With thisin mind, the thickness of the extraordinarily thick ridge of ink 34 willgenerally be slightly thicker and be around fifteen or twenty microns.Typically, the extraordinarily thick ridge of ink 34 will be appliedonto the lenticular split image using a well known silk screeningprocess.

As shown in FIGS. 1 and 3, the thick ridge of ink 34 can be appliedalong the edge of a design or image, such as heart 16, in the lenticularsplit image 26. Importantly, it is to be appreciated that anextraordinarily thick ridge of ink 34 can be applied anywhere onto thelenticular split image 26. Thus, the ridge of ink 34 can be around oracross either the masked or unmasked portions of the lenticular splitimage 26.

In the manufacture of a sign 10, such as a trading card, the particularobject to be reproduced is first analyzed with a view toward making anattractive three dimensional presentation with visual texturingenhancements. For discussion purposes, the object 36 to be consideredhere is the combination of images and designs for clover leaf 12,diamond 14 and heart 16 as shown in FIG. 1. Also, for discussionpurposes, consider that it is desirable to show a three dimensionalpresentation of the object 36 wherein the clover leaf 12 will appear tobe closer to the viewer than the diamond 14, and the diamond 14 willappear to be closer to the viewer than the heart 16. It may also bedesirable to have a foreground which will appear dimensionally to be infrom of the object 36 and a background which will appear dimensionallyto be behind the object 36. Further, to enhance the visual appearance ofthe object 36, it may be desirably to present portions of the object 36(e.g. clover leaf 12 and diamond 14) with a shiny appearance andportions of the object 36 (e.g. heart 16) with a flat appearance. Withthis in mind, consider FIGS. 4 and 5.

In general, FIG. 4 shows a photographic set-up for the preparation oflenticular split image 26 and FIG. 5 shows a photographic set-up for thepreparation of lenticular split covering 28. In all important respects,both the lenticular split image 26 and the lenticular split covering 28are prepared in substantially the same manner. The essential differencebeing that the image 26 and the covering 28 are different visualizationswhich are subsequently printed onto second surface 22 of the lenticularlens layer 18 using different kinds of inks. As indicated above, thelenticular split image 26 will be process printed onto the secondsurface 22 using translucent or transparent inks, and the lenticularsplit covering 28 will be process printed using opaque white inks.

Considering only FIG. 4, for the moment, it will be seen that the object36 has been differentiated into three separate parts, and that theobject 36 is to be presented with a foreground and a background.Specifically, FIG. 4 shows in ordered sequence from front to rear, aforeground plane 38, which in this case is a frame outline, a fore-focalplane 40 on which the clover leaf 12 is depicted, a focal plane 42 onwhich the diamond 14 is depicted, an aft-focal plane 44 on which theheart 16 is depicted, and a background plane 46 which is positioned atthe rear. It is to be understood that there can be several fore-focalplanes 40 as well as several aft-focal planes 44. The fore-focal plane40 and the aft-focal plane 44 are merely representative. Further, itwill be seen that each of the planes 38, 40, 42, 44 and 46 are arrangedas desired at different depth distances from a datum line 48.

As shown in FIG. 4, the foreground 38 is presented on a plane which islocated at a depth distance 50 from the datum line 48. In order, behindthe foreground 38 is the fore-focal plane 40 at a depth distance 52, thefocal plane 42 at a depth distance 54, and the aft-focal plane 44 at adepth distance 56. Finally, there is the background 46 at a depthdistance 58. It is to be appreciated that the planes 38, 40, 42, 44 and46 can be, in fact, transparencies on which the particular background,foreground and parts of object 36 are presented. It is to be alsoappreciated that all of the depth distances 50, 52, 54, 56 and 58 caneach be varied for the transparencies at the respective planes 38, 40,42, 44 and 46. Accordingly, the parts of object 36 can be arbitrarilyarranged to achieve the desired three dimensional presentation forobject 36.

Once the parts of object 36 are arranged as desired, a camera 60, whichuses a lenticular lens (not shown), photographs the arrangement ofobject parts from several different perspectives. For purposes ofdiscussing the present invention, although many perspective viewpointscan be used, only three such perspective viewpoints will be considered.These perspective viewpoints, which are identified as A, B and C, areshown in FIG. 4 and represented therein with the respectively markedcamera positions 60, 60' and 60". All three viewpoints, A, B and C, arepositioned along datum line 48.

In a manner well known in the pertinent art, successive camera positions60, 60' and 60" will be used to create a composite photograph of thearrangement of object 36. First, from viewpoint A a photographic shotwill be taken with the camera using its lenticular lens. Viewpoint Bwill then be used to photograph the arrangement from camera position60'. And, finally, viewpoint C will be used to photograph thearrangement of object 36 from camera position 60". The result is alenticular split image 26. Similarly, in a manner well known in thepertinent art, the object 36 can be created using computer techniques tocreate a composite arrangement.

With reference now to FIG. 6, it will be seen that lenticular splitimage 26, without the assistance of lenticular lens layer 18, appears tothe unaided eye as a series of vertical strips 62. Specifically, thestrips 62 correspond to the A camera position 60, strips 62' correspondto the B camera position 60', and the strips 62" correspond to the Ccamera position 60". More specifically, as best seen in FIG. 6, thestrips 62, 62' and 62" are located in an ordered juxtaposition to createthe lenticular split image 26. Consequently, when the lenticular lenslayer 18 is positioned in register over lenticular split image 26,separate images of the object 36 from the A, B or C viewpoint will beseen depending on the angle of the viewer with respect to the lenticularlens layer 18.

Referring now to FIG. 7, and particularly to the lens 24a which is showntherein, it will be appreciated that from eye position 64 the lens 24awill focus the viewer on a strip 62 which corresponds to the A portionof lenticular split image 26. On the other hand, when sign 10 is viewedfrom eye position 64', the lens 24a will focus the viewer onto strip 62'which corresponds to the B portion of lenticular split image 26.Similarly, from eye position 64", the viewer's focus will be on a strip62" which corresponds to the C portion of lenticular split image 26.Thus, lenticular split image 26 is actually a composite of the separateimages A, B, and C which, depending upon the particular eye position 64,64', or 64", will be individually seen by the viewer. As is well knownin the art, the different perspectives which are afforded by viewingdifferent separate images of the object 36 from the various eyepositions 64, 64', or 64" gives the sign 10 its perception of threedimensional depth.

The lenticular split covering 28 is also manufactured in a mannersimilar to that used for the manufacture of lenticular split image 26.Specifically, and referring back to FIG. 5 for the moment, that portionof object 36 which is to be masked is first identified. Here, forpurposes of discussion, the covering 28 is considered for only the heart16. Once identified, the covering 28 is located in a photographic set upas shown in FIG. 5. Importantly, the covering 28 is photographed whilein the same relationship to datum line 48 as was previously used forthat part of object 36 which is to be masked (e.g. heart 16). Here, thebacking 28 for heart 16 is specifically located in aft-focal plane 44.Note that, although the foreground plane 38, fore-focal plane 40, focalplane 42 and background plane 46 are shown in FIG. 5, no backing 28 isshown in these planes.

Again, just as previously disclosed with regard to the lenticular splitimage 26, a sequence of photographs are taken of the covering 28 fromcamera positions 60, 60' and 60". The result is lenticular splitcovering 28. Lenticular split covering 28 is thus a composite ofseparate aspects A', B' and C' which in every respect are similar to theseparate images A, B and C which constitute the lenticular split image26.

As indicated above, the lenticular split covering 28 is process printedonto the lenticular split image 26 to give the masked portions oflenticular split image 26 a flat appearance. This effect is, perhaps,best appreciated with reference to FIG. 7, and in particular to the lens24b. There it will be seen that the separate aspects A', B', and C'respectively underlay the separate images A, B and C. Consequently,these portions of lenticular split image 26 which are masked bylenticular split covering 28 will have a flat, rather than a shinyappearance.

While the particular 3-D card as herein shown and disclosed in detail isfully capable of obtaining the objects and providing the advantagesherein before stated, it is to be understood that it is merelyillustrative of the presently preferred embodiments of the invention andthat no limitations are intended to the details of the construction ordesign herein shown other than as defined in the appended claims.
